Coleus plant named ‘Balaublach’

ABSTRACT

A new and distinct cultivar of  Coleus  plant named ‘Balaublach’, characterized by variegated foliage of varying amounts of green and grayed-purple, and vigorous, upright bushy growth habit.

Latin name of genus and species of plant claimed: Solenostemonscutellarioides.

Variety denomination: ‘Balaublach’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Coleusplant botanically known as Solenostemon scutellarioides and hereinafterreferred to by the cultivar name ‘Balaublach’.

The new cultivar originated in a controlled breeding program carried outduring January 2002 at Cartago, Costa Rica. The objective of thebreeding program was the development of new Coleus cultivars with uniqueleaf shapes and coloration.

The female (seed) parent of the new Coleus was the Solenostemonscutellarioides variety ‘Ducksfoot’, not patented. The male (pollen)parent of the new variety was proprietary breeding selection 01Co8, notpatented. The new cultivar was discovered and selected by the inventoras a single plant within the progeny of the above statedcross-pollination during August 2002.

Asexual reproduction of the new cultivar, by terminal stem cuttingssince 2002 in West Chicago, Ill., has demonstrated that the new cultivarreproduces true to type with all the characteristics, as hereindescribed, firmly fixed and retained through successive generations ofsuch asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedlyobserved and can be used to distinguish ‘Balaublach’ as a new anddistinct cultivar of Coleus plant:

-   -   1. Variegated foliage of varying amounts of green and        grayed-purple color.    -   2. Upright bushy form.    -   3. Vigorous growth habit.

Plants of the new cultivar differ from plants of the female parentprimarily in foliage shape and color and from the male parent primarilyin foliage color.

Of the Coleus cultivars known to the inventor, the most similar to thenew cultivar is ‘Balaustop’, not patented. However, in side by sidecomparisons, plants of the new cultivar differ from plants of‘Balaustop’ in the following characteristics:

-   -   1. Plants of the new cultivar have longer internodes than plants        of ‘Balaustop’.    -   2. Plants of the new cultivar have more red color in the foliage        than plants of ‘Balaustop’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonablypossible to make the same in color illustrations of this type, a typicalplant of the new cultivar. Colors in the photographs differ slightlyfrom the color values cited in the detailed description, whichaccurately describe the colors of ‘Balaublach’. The plant was grown for7 weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmentalconditions to date. Accordingly, it is possible that the phenotype mayvary somewhat with variations in the environment, such as temperature,light intensity, and day length without, however, any variance ingenotype.

The chart used in the identification of colors described herein is TheR.H.S. Colour Chart of The Royal Horticultural Society, London, England,2001 edition, except where color terms of ordinary significance areused. The color values were determined on Sep. 24, 2004 in West Chicago,Ill., between 10:00 and 11:45 a.m. under natural light conditions.

The following descriptions and measurements describe plants producedfrom cuttings taken from stock plants and grown in a doublepolycarbonate-covered greenhouse under conditions comparable to thoseused in commercial practice. The plants were grown at West Chicago, Ill.in 10 cm pots for 7 weeks while utilizing a soilless growth medium.Greenhouse temperatures were maintained at approximately 75° to 85° F.(24° to 29° C.) during the day and approximately 60° to 70° F. (15° to21° C.) during the night. Greenhouse light levels were maintained atapproximately 4,000 to 10,000 footcandles during the day.
